Abstract

The rigid symmetric rotor dynamic stability in the foil fluid bearings to the influence of the disturbing forces of the lubrication layer and external disturbing rotor forces are examined. The design equations are obtained. Calculation results of the rotor dynamic stability with different variants of the foil fluid bearing and their analysis are presented.

Keywords:

rotor dynamic stability; foil fluid bearings; nonstationary gas lubrication equation; external disturbing rotor forces.
